Hi,
I have the following statement in a function.
UPDATE orderseq
SET orderseq_number = (orderseq_number + 1)
WHERE (orderseq_name='InvcNumber');
All it does is update a single record by incrementing a value (int).
But it never completes. This has to be some sort of bug. Anyone ha

Hi,
In python when I create a method/function is set a default value for a
passed value if one is not provided.
def foo(self, event = None):
In the above function if the second value is not passed a value of None
is used as the default.
Is this possible with plpgsql???

I need to maintain a sync-ed table across several databases. For example I
have a customer table in 5 databases. If a user of any of the databases
inserts a new customer I need to insert the new record into the other four

Hi,
In my app it is possible to login as one name and use a different name to
login to postgres.
Is it possible to get the actual OS login name using plsql.

Hi,
I know this is a newbie question but I have never had the need to do the
following.
I start a transaction.

Hi,
I have read a few articles and I'm not sure if it's me or the authors but I do

If I have table that has a PK and a FK - will the planner use the FK just same
as it would use the PK? IOW's is a FK also an index used by the planner?

As always I respect your insights - Adrian. I do understand what I did wrong
in my first attempt at getting my statement to work. But it is either over my

Hi,
I have need of a statement that updates the sequence but uses a max() to find
the number.
alter sequence somename restart with (select max(pk) from sometable).
I need this for automating an ETL (using pentaho).

Hi,
I just discovered that I can use $$string$$ to account for the problem of
single quotes in the string (or other strange char's). However, I noticed
that the table field contained E'string'. I actually tried to find info on
this but I did not find anything.

I need a little help understanding how to attack this problem.
I need to find the max(date) of a field but I need that value later in my

If I

Hi,
I have a special need to create a sequence like function.
"O-20110704 -2" which is
"O" for order (there are other types)
"20110704" is for July 4, 2011

I of course can get the type and date. What I don't know is how to get is the

By that I mean have some SQL select that will return all the tables a field

I always thought that an insert statement would accept any select statement.
